Beta is a measure of a stock's volatility in relation to the market. It is calculated by comparing the stock's price movements to the overall market movements over a period of time.

Beta is a measure of a stock’s volatility in relation to the overall market. It is calculated by dividing the stock’s volatility by the volatility of the overall market. A stock with a beta of 1 is considered to be as volatile as the overall market, while a stock with a beta of less than 1 is considered to be less volatile than the overall market. A stock with a beta of greater than 1 is considered to be more volatile than the overall market.
Beta is an important measure for investors to consider when making investment decisions. A stock with a higher beta is more likely to experience larger swings in price than a stock with a lower beta. This means that a stock with a higher beta is more likely to experience larger gains and losses than a stock with a lower beta. As such, investors should consider the beta of a stock when deciding whether or not to invest in it.
Beta can also be used to compare the volatility of different stocks. For example, if two stocks have the same beta, then they are expected to experience the same amount of volatility. However, if one stock has a higher beta than the other, then it is expected to experience more volatility than the other stock.
In addition to being used to compare the volatility of different stocks, beta can also be used to compare the volatility of different markets. For example, if the beta of a stock is higher than the beta of the overall market, then it is expected to experience more volatility than the overall market.
Overall, beta is an important measure for investors to consider when making investment decisions. It can be used to compare the volatility of different stocks and markets, and can help investors determine which stocks are more likely to experience larger gains and losses.
